oneness n. earnest, or cirv, i/n-ssonniiv Be it known that l, CHARLES H.Snvuonv a citizen'of the United States, residing at Kansas City, inthejcou'nty of Jackson and State of M issouri, have invented certain newand useful Improvements in lililkingddachines, of which the following isa specification. j

My invention relates to milking machines.

The object of my invention is to provide a milking machine which may bequickly attached to or detached from an animal and improvements in whichwill readily conform itself to difierent animals. a A' further object ofmy invention is to provide means by which the machine may be attachedto. a plurality of teats and the milk drawn from the teats inconsecutive order so as to simulate the action at milking by hand.

' A further object of my invention is to provide an inexpensivelyconstructed, compact and durable milking machine by means of which ananimal may be quickly and cleanly milked.

Each cylinder 1 at its upper or inlet end isprovided with a vertical, resili- 1 out, tubular extension 2, adapted toencircle a teat of an animal and composed preterably of soft rubber. Iprovided at its lower end with a downwardly and inwardly inclinedtlibularentension 3 which serves as an outlet for the milk. Thecylinders l are clamped to the outer periphery of a horizontal ring a towhich the cylinders are clamped by means of plates 5. The ring 4' issupported by two vertical standards e-updna horizontal an base 7, onwhich are rotatively mounted (in horizontal axes, fourpinions 8 whichmesh with a horizontal intermediate crown gear fipecicflcation ofLetters intent.

wheel 9, which is rotatively mounted on a tubular extension 10, whichextends down wardly from the base 7 The pinions 8 are provided each witha crank pin 11. A plurality of links 12 are respectively pivoted attheir lower ends to the crank pins 11 and their upper-ends arerespectively pivotedto the .lower ends of tour piston rods 13. Saldpiston rods extend respectively through the convex in form, the upperendbeing the convex end.- Each piston 14 is provided with enter more smallholes 15, which eX tend from the lower t'o'the upper ends of the piston.n3; reason of theresilient material or which, the istons 1a are formedand by reason of the orm of each piston and of thesmall size of theopenings 15, said openings willbe closed by the contraction of thepiston when the wardly and-will open when the piston moves upwardly topermit the passage downwardly ot the milk throughthe piston. 'I'preferto employ this kind of a piston to one which is provided with anordinary valve, for the reason that milk, being of a sticky nature, willcause ordinary valve to stick and be come inefiee. .ve, which'is not thecase with theconstruction which I employ.

Each piston 14 is secured to its piston rod by means of two nuts 16which are mounted on the screw threaded upper end of the piston red atopposite sides of the piston. The piston rods 13 may be packed wherethey enter the lower ends of the cylinpiston moves downders l byordinary externally screw threaded packing rings 17, which respectivelyencircle the rods 13 and are respectively. fitted in screw threadedrecesses provided in the lower ends of the cylinders. In said screwthreaded' recesses is provided packing ma terial 18, which encircles therods 13 and is held in 'osition by the packing rings 17. Rotativegmounted on a projection it) which enemas upwardly and outwardly from.the ba e, 7,, is spur driving gear wheel 20, which meshes with theintermediate gear wheel 9, and is provided with a t 21 by means of whichthe driving gear with a laterally extending handle 22 by which theoperator may support the machine with one hand while he is turning thecrank 21 during the milking operation. A vertical discharge tube 23,-extends through the base 7 and is fitted in the tubular extension 10.The upper end of the discharge tube 23 is provided with four upwardlyand outwardly extending tubular upon the tubular extensions theintermediacy of the intermediate gear wheel 9, thusimpartingre'ciprocation to the pistons 14 by means'of the piston rods13,

links 12, and crank pins 11.-

It will be noted that the crank pins 11 in the pinions 8, which arediametrically op posite each other, are disposed respectively in saidpinions in diametrically opposite positions. By means of thisconstruction two oppositely disposed pistons will be simultaneouslyforced in opposite directions. Asthe pistons move downwardly ,a partialvacuum will be formed in each cylinder above the piston, thus drawingthe milk from the teat into the'cylinder. By reason of the pistonsmoving simultaneously in opposite directions, the suction effect inopposite cylinders will be produced therein in consecutive order, thussimulating the operation of milking by hand.

When the pistons 14 move upwardly the milk which has entered thecylinderswill pass from above the pistons to the lower ends thereofthrough the openings 15 and will then pass through the loutlets 3 intothe branches 2-1 from which it will pass into the tube 28. From the tube23 the milk may be discharged into any suitable receptacie.
